Description

一种废旧轮胎破碎单元及其废旧轮胎处理系统 技术领域
本申请涉及固体废物处理系统技术领域，特别是涉及一种废旧轮胎破碎单元及其废旧轮胎处理系统。
背景技术
随着汽车工业的快速发展，越来越多的废旧轮胎长期露天堆放，形成黑色污染的同时，还侵占了大量土地。而废旧轮胎是一种较优质的可燃废弃物，其燃烧时的热值比燃煤的热值高20～30％，因此长期放置无疑是一种燃料资源的浪费。同时水泥行业的发展需要大量的燃料，随着燃煤的价格上涨，近年来出现了燃煤上的供应紧缺的问题，亟需开发出更多替代燃料来取代化石燃料。
为此世界各地的一些水泥厂逐渐开始将废旧轮胎作为替代燃料进行开发和生产，如专利号为“201721162715.2”，专利名称为“一种废旧轮胎替代部分水泥窑燃料的处理系统”公开了一种如何利用废旧轮胎作为替代水泥窑内燃料的处理系统，该系统包括粗碎机、细碎机、钢丝分离机和传输机，通过粗碎机先将废旧轮胎进行一级破碎，形成废旧轮胎粗碎片，然后通过细碎机将废旧轮胎粗碎片进行二级破碎，形成废旧轮胎细碎片，钢丝分离机则用于将废旧轮胎细碎片进行三级破碎并将混有的钢丝分离去除，得到废旧轮胎燃料碎片，最后通过传输机将废旧轮胎燃料碎片输送至水泥窑中，进行燃烧，以替代部分水泥窑燃料。但在使用上述系统实际进行处理时发现：如果一次向粗碎机输送废旧轮胎太多，不仅会给粗碎机带来较大的负载，而且废旧轮胎重叠地方往往破碎效果不好，会残留很大的轮胎碎块，当这部分块径很大的轮胎碎块送入细碎机时，对于细碎机来说负载同样也很大，而且还容易损坏细碎机的刀具，从而影响后续的生产。因此如何更好地、更多地避免上述问题，保证生产的顺畅性成为当务之急的技术难题。

优选地，所述上料给料机内设有打散装置。
优选地，所述上料给料机和所述碎料上料输送机之间设有用于称重的皮带秤。

2.本申请中的第二分散输送机的输送速度是第一分散输送机输送速度的3～5倍，能够使第二分散输送机上的废旧轮胎具有一定的间距，从而避免废旧轮胎重叠影响破碎效果，以及避免废旧轮胎靠的太近，如贴合而使得废旧轮胎掉入破碎机时机相差不多，而在破碎机内出现重叠情况。

实施例1
本实施例公开了一种废旧轮胎破碎单元，如图1至图3所示，包括受料斗1、第一分散输送机2、散料挡板3、第二分散输送机4以及破碎机6。第一分散输送机2位于受料斗1出料口的下方，用于接收受料斗1内废旧轮胎，并将叠在一起的废旧轮胎进行第一次分散，使废旧轮胎一个一个输送出去，作为优选地第一分散输送机2选用链板输送机，链板输送机可承受较大输送量，且最大输送角度较普通皮带输送机大，具有较大的倾斜角度可将物料提升，减少设备占用空间。散料挡板3位于第一分散输送机2的出料端的下方，散料挡板3整体朝向第一分散输送机2的输送方向倾斜，第一分散输送机2的出料端掉落的废旧轮胎会先落到散料挡板3上，在重力作用下重复的废旧轮胎能够被散料挡板3分开，从而实现第二次分散效果。第二分散输送机4的进料端位于散料挡板3的下方，即第一分散输送机2的出料端的下方，用于承接散料挡板3上掉落下来的废旧轮胎，第二分散输送机4的输送速度大于第一分散输送机2的输送速度，以使掉落在第二分散输送机4上的废旧轮胎拉开间距，避免出现重叠现象，实现第三次分散。破碎机6位于第二分散输送机4出料端的下方， 经过前面三次的分散之后，能够保证废旧轮胎一个一个进入破碎机6内进行破碎，从而降低对破碎机6的负载，同时避免出现因废旧轮胎重叠而无法破碎的地方，提高废旧轮胎破碎效果。破碎机6选用市场上常用的满足破碎进出料粒度要求的破碎机即可，作为优选地可选用市场上一种一体化的破碎机6，该破碎机6由进料溜子、回转式剪切破碎刀组和外滚筛组成，物料通过进料溜子进入破碎机6内，进料溜子两侧也有挡板防止速度快的废旧轮胎飞出，随后废旧轮胎进入回转式剪切破碎刀组进行破碎，破碎后的废旧轮胎碎块在不断旋转的外滚筛的作用下，合格的废旧轮胎碎块输出破碎机6，不合格的物料被带回到回转式剪切破碎刀组重新破碎，直到合格后排出破碎机6。
工作过程：首先，通过铲车9将废旧轮胎料堆19中的废旧轮胎铲起并投入受料斗1内；然后，第一分散输送机2承接受料斗1的出料，并对废旧轮胎进行第一次分散，随后将废旧轮胎输送至出料端；再然后，从第一分散输送机2的出料端掉落的废旧轮胎会先落至散料挡板3上，从而实现第二次分散；再然后，散料挡板3上掉落的废旧轮胎在第二分散输送机4输送下，实现第三次分散，随后将废旧轮胎一个一个输送至破碎机6内；最后，在破碎机6的破碎下实现破碎。
进一步，本实施例中，如图1至图3所示，第二分散输送机4的输送速度是第一分散输送机2输送速度的3～5倍。以保证第二分散输送机4输送的废旧轮胎均具有一定的间距，避免出现废旧轮胎重叠情况，以实现一个一个向破碎机6输送废旧轮胎，甚至能够保证相邻的废旧轮胎不会贴合，避免废旧轮胎掉落时贴合较近，在破碎机6内重叠。
进一步，本实施例中，如图1至图3所示，第二分散输送机4出料端和破碎机6之间设有轮胎上料输送机5，轮胎上料输送机5的进料端位于第二分散输送机4出料端的下方，破碎机6则位于轮胎上料输送机5的出料端的下方。轮胎上料输送机5的输送方向与第二分散输送机4的输送方向相同，且轮胎上料输送机5的输送速度大于或等于第一分散输送机2的输送速度。通过设置第二分散输送机4优选整个废旧轮胎破碎单元的布置，进行相应的调节。

本实施例公开了一种废旧轮胎处理系统，如图1至图3所示，包括实施例 1中的废旧轮胎破碎单元、暂存输送单元、上料输送单元以及燃烧单元。废旧轮胎破碎单元用于将整个或大块的废旧轮胎破碎碎成废旧轮胎碎块，暂存输送单元则负责将废旧轮胎碎块暂存或直接输送至上料输送单元，然后通过上料输送单元将废旧轮胎碎块送至燃烧单元作为燃料进行燃烧。上料输送单元包括上料给料机10、碎料上料输送机12和振动给料机14，上料给料机10上自带有料斗，碎料通过料斗可进入上料给料机10内，碎料上料输送机12位于上料给料机10的出料口下方，振动给料机14则位于碎料上料输送机12出料端的下方，振动给料机14将废旧轮胎碎料打散并输送至燃烧单元进行燃烧。作为优选地，碎料上料输送机12可采用管状皮带机，管状皮带机输送角度大一般在25°左右，而普通皮带机一般最大在18°，且管状皮带机密封性好、布置灵活(可水平转弯)。
工作过程：首先，将经过破碎机6破碎的废旧轮胎碎料输送至暂存输送单元，随后通过暂存输送单元输送至上料输送单元的上料给料机10内；然后，碎料上料输送机12将上料给料机10输出的废旧轮胎碎料输送至振动给料机14，通过振动给料机14的振动将碎料打散输送至燃烧单元，以保证燃烧效果；最后，通过燃烧单元将轮胎碎料当作燃料进行燃烧，提供热量或动力等，该系统可广泛应用于各种需要燃料的工厂中，如水泥工厂中作为水泥窑的燃料使用。
本实施例中，如图1至图3所示，上料给料机10内设有打散装置15，可将废旧轮胎碎料进行预打散，以提高振动给料机14给料效率和分散效果。
进一步，本实施例中，如图1至图3所示，上料给料机10和碎料上料输送机12之间设有用于称重的皮带秤11，通过皮带秤11可实现定量供料，皮带秤11的进料端位于上料给料机10出料端的下方，碎料上料输送机12的进料端位于皮带秤11的出料端。
进一步，本实施例中，如图1至图3所示，碎料上料输送机12与振动给料机14之间设有短皮带机13，通过短皮带机13可调整整个上料输送单元的走向，同时将废旧轮胎碎料输送给振动给料机14。短皮带机13的进料端位于碎料上料输送机12的出料端下方，振动给料机14则位于短皮带机13的出料端的下方。
本实施例中，如图1至图3所示，燃烧单元包括水泥窑，水泥窑的分解炉的废旧轮胎进料口18位于振动给料机14出料端的下方，以将废旧轮胎碎料作为燃料进行燃烧。
进一步，本实施例中，如图1至图3所示，分解炉的废旧轮胎碎料进料口18的进料口处从上到下依次设有电动双翻板阀门16和气动插板阀门17，电动双翻板阀16用于锁风，电动双翻板阀门16的两层翻板交替打开和关闭，能够避免系统漏风；气动插板阀门17是常开的，在紧急情况时关闭，将物料和分解炉内的热气体分隔开，保护上游设备。
本实施例中，如图1至图3所示，暂存输送单元包括轮胎出料输送机7和暂存料堆8，暂存料堆8用于暂存废旧轮胎的碎料。轮胎出料输送机7的进料端位于破碎机6的下方，轮胎出料输送机7的出料端位于暂存料堆8上方，用于将废旧轮胎碎料排至暂存料堆8，然后通过铲车9将碎料废旧轮胎碎料送至上料给料机10中。
本申请中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的方法及其核心思想；同时，对于本领域的一般技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处。综上所述，本说明书内容不应理解为对本申请的限制。
